we are traveling to Mexico for the first time. We will be traveling with a 7 years old daughter. We will be staying at Grand Palladium Colonial Resort & Spa. We also plan to rent a car for the week. What are the local attractions worth seeing? Also, how safe is it to do it on your own vs. trips you can buy at the hotel? Any suggestions including the approximate cost are really appreciated. Is it better to pay in US $ or exchange money there and pay in pessos?
